Bitcoin (BTC) Layer 2 Scaling Solution, Fractal Bitcoin, Significantly Increased Its Network Security

Bitcoin’s layer 2 scaling solution, Fractal Bitcoin, significantly increased its network security by onboarding one of the largest crypto mining pools.

According to a Thursday report by crypto news outlet Token Post, Fractal Bitcoin (FB) has managed to secure Foundry, one of the largest Bitcoin (BTC) mining pools, to also start mining FB.

This was a goal that Fractal Bitcoin set out to achieve earlier this year, aiming to get 90% of Bitcoin’s hashrate to also mine Fractal. With Foundry’s integration, it has now reached 93%.

This, in turn, makes it the most secure Bitcoin-compatible network, which is in line with Fractal’s goals to leverage Bitcoin’s security while also maintaining the scalability necessary to power complex DeFi applications.

According to the report, most miners use their resources to mine on several chains, such as Bitcoin, Litecoin, Doge, or Monero. This is despite the fact that mining on each network typically requires separate computing and energy resources. Still, depending on token prices and mining difficulty, it is advantageous to split resources.

Fractal and Bitcoin use the same hashing algorithm, SHA-256. Notably, networks that use the same hashing algorithm support merged mining. This means that miners can secure both networks at once, using the same computing power they would when securing just one chain.

For this reason, Fractal Bitcoin can easily onboard Bitcoin miners who can get additional rewards without much cost. However, Bitcoin miners don’t get all the rewards, as Fractal Bitcoin uses the Cadence Mining model.

This model splits block rewards between merged and permissionless mining, with one-third of the rewards going to Bitcoin miners. The other two-thirds go to anyone with the right hardware. This broadens access, as potential miners don’t have to rely on costly BTC mining infrastructure.
